I’m a UX researcher who became my own product team and… think I owe some PMs an apology. 😅 I’ve spent YEARS being the researcher saying: “But users really need this. Can we get it into this release?” Then I started building Cuewise, a side project for people who spend more time picking something to watch than actually watching it. Now I have a ridiculous backlog of things that would genuinely make it better. (Some are mine. Some are courtesy of my extremely enthusiastic Replit agent.

See what ChatGPT, Gemini, and Perplexity recommend across 15 SaaS categories.

I asked ChatGPT, Gemini & Perplexity what they'd recommend in 15 SaaS categories (450 answers).

Analyze what ChatGPT, Claude, Gemini and Perplexity recommend in your category and who they suggest instead of you.

I built a free tool that shows who AI recommends in your category (and who it names instead of you) When you ask ChatGPT, Claude, Perplexity or Gemini for the best tool in a category, they recommend the same few incumbents and quietly skip everyone newer. Most founders have no idea whether AI is recommending them or their competitors. So I built Bersyn. You type your domain, it asks the four models the questions your buyers actually ask, and shows who gets recommended in your category, who
